Irregular Hips, Warped Eyebrow One Side, Trussed, Double Tails Sticked

UpNorth

I've shown this design here before. It'll get built this summer, and we'll post in-process pics then.

A small set of engineered trusses frame the roof, which comes to a point, and has irregular hips. The lookout side has a warped eyebrow at center, with single spring-arch window under.

Framed on top of 7-foot walls, the trusses have 2x6 heel raise blocks which effectively frame the perimeter soffit, and allow for all the blown cellulose depth we want in the ceiling.

The twin 2x4s that make for each set of exposed tails, are dropped from the roof plane to permit beveledge planking at the overhangs, with sheathing over all.

Planking and sheathing will require some bending and warping, but the crew that will do it has done these before and says "no problem."

The inside views show how the ceiling planes all work out.

If anybody says that you can't do a complex roof with trusses, here is the proof.

UpNorth

. . . and others here will agree (and tell us so), but setting the trusses will go quickly, and a lot of the ceiling framing will be there as an end-result.

Local truss plants are starving, and selling packages at incredible bargain prices.

The scroll-cut double tails would be the same, either way.

I think that is great. Designing the truss systems to accommodate an efficient building technique is a good thing. It's not feasible in every situation, but this one can certainly handle it.

I would go one more step and use a better hip truss system though. If you like, I can post the link to a much better system that uses less jobsite materials, eliminates most if not all of the hangers you will need on your system, and be able to have the framing crew install it quicker.

As a framer, I wouldn't want those double tails attached by the truss company. If you want it looking nice, give me the parts, not the truss company.

Please post the link for the better hip truss arrangement. The dropped-with-jacks setup shown in the model is one the trussmaker has done for us before. We'll see how he feels about progress.

Tails are not in the truss package. They will be either WRC or DF.

It looks interesting. It will be nice to see the progress pics. When you say "irregular hip" do you mean a bastard hip?

Here is the pdf file I made a few years back. I am trying to locate in my files the 3d model to send you.

This is the thread I started about the system. I used this system all the time on the west coast with a few small modifications. I came back here and had the system you show. It's not horrible, but there are easier ways to get it done with less cost and zero field framing.

Your job would be complete from the truss company. No extra material necessary for overframing.

The major cost is the hip masters. The hips and jacks are just 2x4's (if you want)

Thanks. Looks like it is what some trussies call "California" or some variation thereof.

We'll see what the local truss guys say. What they are used to and build and ship, is called "Northeast."

It may be more difficult to achieve the ceiling shape with this, but maybe not.

Use the cal hip. I had a hard time a few years ago build cal for me they did the what your calling northeast hip always. Now they do it almost all the time. There should be no prob with your ceilingbut they may balk at something new to them, I know i argued alot. The cal hip is the easiest, most in plane system you can use.

KentWhitten

The only difference is the jack package, the hip itself, and the horizontal member on the hip trusses are dropped to allow the jacks to go over. It doesn't affect your arc area in the least. If they can move things around and design an eyebrow into a truss system, they surely can do the hip package differently.

Kent,

The last house we used trusses on was 2006 I think. It had the system you are talking about.

That's the one. Thank you for posting that Tim.

It took the picts from Tim for me to understand what you have been telling us.
It does look better than our current way of doing it.

Bet you will get a lot of flack from local framers though.

KentWhitten

Though it is tough for you to decide since you haven't done one, wouldn't you say that this is a much easier system to install?

The installation steps for this system would go like this:

• Set hip masters, h1's, h2's, etc.
• install all jacks with 8' bottom chord (to the hip master)
• install (3) 2' bottom chord jack packages (each corner)
• slide hip through the jack top cuts

The hips slide right through easily and are held in place by the flat tops of the hip masters. Very easy to manipulate.

It completely eliminates all hangers on the hip master. It completely eliminates the hip girder. It completely eliminates field work past the hip master.

I'm going to have to find the model file and do an exploded view to give everyone a clearer picture. North's package, from what I can see, would require zero hangers and I dare say, it would be a cheaper price tag.

The only downside I see to that is not being able to prebuild it on the ground. We build all out hip carriers (Hip master?) on the ground and lift them ourselves. Saves a but load of crane time. Gives all trusses that are craned in a good point to anchor to as all the jacks are set, nailed off and secured.
